Retired HVAC Pro? Ductless Mini Slim Help

Knoxville TN

Description

I've purchased a Çooper & Hunter Mini Split. I've built a detached garage. I've prewired 230. I'm preparing to mount exterior and interior sections. I'm pretty technically good; having been in construction most of my life. However; I'd like some help as I know this unit is pre-charged; there is something about needing to apply vacuum pump; letting nitrogen out of line set etc. This is beyond me. I'm not asking this entire unit be installed; that process is straight forward. But, I'd gladly pay if you've the tools to assist in line test etc. I'll likely have lines run, no coils, straight shot. Perhaps Thursday or Friday this week? Cash pay. Experienced only please.
